Parsley and Butter
Ingredients
Directions
Prepare the parsley
Wash the parsley thoroughly and pick the leaves off carefully.
Add the salt to the boiling water and boil the parsley for about 10 minutes.
Drain the parsley in a sieve, then mince it finely and bruise it to a pulp.
Make the sauce
Place the minced parsley in a sauceboat and gradually mix in the melted butter.
Do not add flour, as the parsley will thicken the sauce.
Serve
Serve the parsley and butter in the sauceboat, not poured over the dish.

What each ingredient does
- Fresh parsley leaves
- Provides the main herbal flavour and, once bruised to a pulp, thickens the sauce naturally.
- Melted butter
- Adds richness and a smooth, fatty body that carries the parsley flavour.
The step that matters
Gradually mixing in the melted butter. Adding the butter slowly, while the minced parsley is pulverised, lets the butter emulsify evenly with the parsley pulp. Pouring it in all at once can leave the sauce greasy and separated.
